They keep saying the idea of a Weekly Sabbath synchronized to the month comes from Pagan Babylon. This is literally the Opposite of the Truth.
From the Seven Day Week Wikipedia page's History section.
While the seven-day cycle may have deep historical origins in the Ancient Near East, the "planetary theory" of horoscopy is a development of Babylonian astrology roughly around 500 BC, with the oldest extant horoscope dated to just before 400 BC.
The seven-day week being approximately a quarter of a lunation has been proposed (e.g. by Friedrich Delitzsch) as the implicit, astronomical origin of the seven-day week, and indeed the Babylonian calendar used intercalary days to synchronize the last week of a month with the new moon.Meaning the oldest references to a Week like concept to occurs in Ancient Mesopotamia were using something probably not identical to the modern Lunar Sabbath concept, but the same basic logic behind it. Sumerian Texts and the Enuma Elish seem to imply every Full Moon was a Sabbath.
The Astrological idea of affiliating the Days with Planets not showing up till 500 BC, means they didn't show up till after the Babylonian Captivity, and well after the Assyrian. So there is no evidence of a strict seven day week not synchronized to a new moon that can be proven to exist independent of Jewish and/or Christian influence. Which backs what I proposed in The Manna Miracle and The Sabbath.
The people running Wikiepdia of course want to convince people that the idea of a Week was borrowed by the Israelites from Babylon. But we know better.
The Lunar Sabbath model also argues for a Friday Crucifixion, which I have firmly refuted.
